RAIL-STOP FO R RAILWAY ROLLING-STOCK.

Specification of Letters Patent.

Application filed May 31,1912. Serial No. 700,729.

To all whom it may concern:

Be it known that I, JAMES H. BALL, a citizen of the United States,-and a resident of Calumet, county of Houghton, State of Michigan, have invented certain new and useful Improvements in Rail-Stops for Railway Rolling-Stock, ofwhich the following is a full, clear, and exact description.

The invention relates to a rail lock or stop for railway rolling stock and seeks to provide'a simple, effective construction which is adapted to be secured to the rail to block the movement of locomotives or cars.

The invention consists in the features of improvement hereinafter set forth, illustrated in the preferred form in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan View of the improved rail stop or look. Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1. Fig. 3 is a detail horizontal section on the line 33 of Fig. 2, and Figi is a cross-section on the line 44 of Fig. 1.

The body' portion-10 of the improved rail lock or stop is adapted to extend over thehead 11 of the railway rail 12. In the form shown, the body portion is provided with a raised central part 13 having a flat, upper face a, inclined end faces I) and c, a concaved face d on one side and a convex face 6 on its opposite side. This body portion may be otherwise formed. The particular shape shown can be readily grasped by placing the thumb against the concave side face d and the fingers over the convex side face 0.

The body portion is provided with suitable means whereby it may be securely fastened to the rail and for this purpose is pro- 'vided with depending side portions or flanges letand 15. The side flange 1 1 is somewhat wider than theside flange 15 and is provided at its lower edge with an in-.

turned lip 16. This side flange is adapted to fit against one side of the head 11 of the IZillrWith the lip 16 extending beneath the head of the rail and abutting against the web thereof, as most clearly shown in Fig 4. The opposite side flange 15 is provided at its lower end with an inturned lip 17 'ofrectangular section and a wedging key 18 is adapted to fit between the flange 15 and shown in Fig. 3, so that, as

' with longitudinal the adjacent side of the rail head tosecurely clamp the stop body in. position. The key is preferably provided on its outer side with a longitudinally extending groove 19 within Which the lip 17 extends, the lip and the bottom wall of the groove being inclined. or tapered, as

most clearly the wedge is forced into the position shown'between the side flange 15 and the rail'head, the opposite side flange 14 of the lock body and lip 16 thereon will be drawn snugly into engagement with the head of the rail. Preferably,

as shown, the upper face ofthe wedge engages the under side of the upper portion of the lock body and the inner face of the wedge or key side of therail head, the key being provided with a lip 20 which extends beneath the head of'the rail. To lighten the wedging key, itis provided on its upper and lower edges grooves 21 and, to prevent the lossof the he is preferably connected to the lock body by a chain 2 n the form shown, the chain is fastened at its ends to perforated, laterally projecting lugs 23 and 24 upon the adjacent, side end portions of the lock body and the wedge. This chain, (see Fig. 2) is of sufiicient length to permit the withdrawal and insertion of the wedgcure the lock body to the rail or release it therefrom. The lips 16 and 17 on the side flanges are sufliciently far apart to permit the passage of the rail head between them when it is inclined to one side at an angle of about 45. I i

The body is placed on t-l1'e'-=-rail by inclining it to one side, placing the lip 16 against o"ne side of the web beneath the rail head and rolling the body lock body is then slid to desired position adjacent the wheel of the locomotive or rail-way car and secured in position by over the rail. The

the inner edge of is adapted to fit against the mieomewhat above the tread of the rail. A

, stop dog 28 extends through an inclined guide-way 29 in the body of the stop device f and is preferably held in position by a pin 30 which fits in an opening in the dog and 355 extends through'a slot 30 formed in the lock body at right angles to the guide way 29;

The guide-way 29 is inclined at an angle of to the horizontal and the stop dog has a limited motion therethrough to the extent 2; allowed by the pin and slot connection be- "tween it and the lock body. The construe tion is such that the stop dog is held above the center of the rail and its upper end is arranged to engage the tread 33 (see Fig. 2) of the locomotive or car wheel. Prefers ably, the upper, wheel engagingend 34'of the stop dog is slightly rounded or crowned, as shown, to properly engage worn wheels and also to allow for the angle of the wheel 30. tread.

The stop dog is Preferably formed of carbon steel. Its lower end 35, which is adapt- .ed to engage the tread of the rail, is chisel hardened and ground at right angles so that knife edges 36 are. provided. Any movement of the locomotive or railway car will exert pressure on the stop dog and. one of the knife edges 36 will bite into the rail to thereby prevent movement of the stop dog and of the locomotive or railway car. Preferably, the stop dog is made as short as possible, but it should be of sufficient length to prevent the wheel or any portion of the wheel from. engaging the body of the stop device.

' The improved rail lock or stop is preferably used in pairs, one being of right hand and the other of-left hand construction and so arranged that the wedging keys are placed upon the outer side of the rail.

A pair of improved lugs or stops can be readily placed in position and engaged with the wheels of a locomotive or car for blocking the same against movement.

The improved construction i particularly adapted as; safety device blocking locomotives in roundhouses and at raii way terminals. It can also be used l1 convenience in car repair sho s. By mg a car against one of the improved stops, the end of the car may be raised ror convenience making repairs. The 0021* struction is inexpensive and of light weight and can be readily and conveniently placed in position and theref dni. By

driving out the pin 30, the stop dog can be removed and its lower, rail engaging end resharpened.

It is obvious that changes may be made in the details set forth withoutdeparture from the essentials of the invention as dofined in the claims.
